Problem Running conexp-clj on OS X

[exot]

Hi Eugen,

thanks for reporting this. I have just removed the -f switch from the script, but since I do not have access to an instance of OS X, I cannot test the new script. Could you check if it works?

In any case, to start the GUI you can just write

(use 'conexp.contrib.gui)
(gui)

in the repl, and this should start the GUI.

First of all, thanks, your change helped a bit. Namely the error message is now only

usage: dirname path
Error: Could not find or load main class jline.ConsoleRunner

After some investigation I installed jline-1.0.jar into /Library/Java/Extensions but was greeted with another error:

usage: dirname path
Exception in thread "main" java.lang.ClassNotFoundException: clojure.main
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
at java.net.URLClassLoader$1.run(URLClassLoader.java:355)

at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:186)
at jline.ConsoleRunner.main(ConsoleRunner.java:73)

I could not find a solution for this, so I tried running the gui from source. At first I thought everything was fine and the GUI Icon as well es the top menu was there. But the main window itself did not show up and the program froze so I had to kill it.

What a pity, but thanks anyway for your effort.

Eugen, thanks for your investigations. It is kind of awkward that dirname is not working the way it is supposed to be, but that may be only the result of another error. As I do not have access to any Apple, I cannot fix that now, but I will try to find someone who is willing to lend me his/her computer.

As for the freezing GUI, I would have some questions: what java implementation are you running on? Are there any errors showing up? What exactly appears and what not?

I finally found the time to reply to your questions:

This is the output of java -version:

java version "1.7.0_06"
Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)

For some reason I do not get the GUI I was remembering 20 days ago when entering your commands, so I can't really tell you more about the specific problems. Here is what I see:

Hm, I thought that error would be gone, but as it seems, my knowledge about Java pipes and threads is not complete. For now, I just disabled the repl in the GUI, i.e., this IOException should not appear anymore. Can you try again and see if the GUI still freezes?

Thank you!

Daniel, everything works fine know when I try to run the GUI from source ;), thanks!

There was only one tiny problem: The main window that pops out after having entered (gui) is really tiny and in the upper left corner of the screen so at first I did not even find it. Apart resizing it, everything is fine, though.

It seems that calling pack! caused this problem. I removed that call and specified some (arbitrarily chosen) dimension values for the frame. At least on my system this has the desired effect that the window shows up larger.

[eugenkiss]

Yes, that fixed it!

Great! Thanks for reporting and being so patient ;)
